Wilstone Reservoir Tring - Colourful Insects

A walk a couple of weeks ago in the wonderful September weather around Wilstone Reservoirs revealed a number of interesting insects in the field behind the bird hide.

My first ever 'Hornet Hoverfly'  (I believe Volucella zonaria), the UK's largest hoverfly, loosely .  Two were hanging around the entrance to a wasp's nest in the long grass and I was able to get a few photos.  Afterwards I realised I had missed taking a photo of a wasp to compare sizes, the hoverfly being larger than the wasps.  According to the field guide their grubs live in the wasps nests, so I suppose they were waiting to enter the nests to lay their eggs.



Vagrant Hawkers were abundant patrolling the hedge line.  I was lucky enough to spot this one resting on a blackthorn


 
Later on I came across this spider that seemed to be struggling to remove a bird feather from its web.
 Finally I came across this camouflaged Common Darter (female I think), resting on the seedhead of the grass.
